水资源短缺和地下水超采是北京的基本水情,水资源供需矛盾突出是首都可持续发展的主要瓶颈,面对水资源现状,北京市启动了最严格的水资源管理制度。而水资源论证就是在保障建设项目的合理用水前提下,提高用水效益和效率,减少建设项目取水和退水对周边的不利影响,也为取水许可的科学审批提供决策依据,从而严格水资源管理制度。根据多年进行水资源论证的实例,总结了取用不同水源的建设项目水资源论证的要点,提出了水资源论证中的难点及相应的解决措施,为北京市建设项目水资源论证提供参考。
Water scarcity and over-exploitation of groundwater are the basic water regimes in Beijing. The prominent contradiction between supply and demand of water resources is the main bottleneck for the sustainable development of the capital. Beijing faces the most stringent water resources management system in the face of water resources. The demonstration of water resources is to protect the construction projects under the premise of the rational use of water, improve water efficiency and efficiency, reduce construction projects to withdraw water and backwater on the surrounding adverse effects, but also for the scientific approval of water licensing to provide decision-making basis, and thus strict water resources management system. According to the example of water resources demonstration for many years, this paper summarizes the key points of water resources demonstration of construction projects with different water sources, puts forward the difficulties in water resources demonstration and corresponding solutions, and provides reference for water resources demonstration of construction projects in Beijing.
